Porsche 924s 2.0Already Tried: new coil
Greetings! With the key on, make sure there is full battery voltage at the coil and with a test light, check to see if there is a ground signal trigger when cranking. THis is the signal at the coil that starts the spark process from the coil.
how do I check to see if there is a ground signal trigger?
How do I check to see if there is a ground trigger signal?
Take the alligator clip of the test light and clip it on battery positive. Take the tip of the test light and touch the other wire on the coil (not the power wire) and crank the engine over. THe test light should blink.
Test light does not blink @ negative side of coil while cranking.
Test light does not blink @ neg. side of coil while cranking.
This means the computer is not seeing a crank signal.
